H.G Wells book covers

I recently designed some H.G Wells book covers for a D&AD competition. The aim was to create a set of covers that worked well together. My concept brings together a set of icons which symbolically relate to main themes or events within each story:

Tono Bungay - Tonic (bubbles)
Love & Mr Lewisham - Love (heart)
Mr Polly - Destruction (flames)
Ann Veronica - Freedom (butterfly)
Each book also had references to science some of which were subtle. I used structured line/diagrammatical marks, repeat patterns and fluorescent colours to illustrate this.
